This [covariance] is something that is not in the habit of thinking of most amateur investors. They look at their investments one at a time, and they don't, you always have to go back and say, what's the covariance? That's what really matters for what happen to your portfolio. Because when you invest in a lot of companies that are all the same, you're asking for trouble, because the whole thing is going to either blow up or succeed. And you can't live like that. You have to be looking for low covariance.

People may be prepared to buy services from Apple and Amazon if they feel these companies do a good job, but we need to ensure that we can speak up when our content is used by other people for their profit. An activist amateur culture will constantly challenge and say, 'This is mine, you're not doing that with it.'

Fantasy sports went a long way toward developing the sabermetrics formulas used not only by oddsmakers but general managers in hiring players. So the amateur fantasists ended up creating some of the algorithms that Oakland GM Billy Bean's statisticians used to win games with less salary money available for star players.

The chief innovator of symbolism in algebra was François Viète... an amateur in the sense that his professional life was devoted to the law... John Wallis... says that Viète, in denoting a class of numbers by a letter, followed the custom of lawyers who discussed legal cases by using arbitrary names [for the litigants]... and later the abbreviations... and still more briefly A, B, and C. Actually, letters had been used occasionally by the Greek Diophantus and by the Hindus. However, in these cases letters were confined to designating a fixed unknown number, powers of that number, and some operations. Viète recognized that a more extensive use of letters, and, in particular, the use of letters to denote classes of numbers, would permit the development of a new kind of mathematics; this he called logistica speciosa in distinction from logistica numerosa.
